Calcite is a carbonate mineral and is the most stable polymorph of calcium carbonate. Calcite can be traced back to ancient Greece, where it was derived from the Latin word calc, meaning 'lime' because it contains crystallized limestone, allowing it to come in a variety of colors. This stone can open and activate the chakras and is sometimes referred to as the vitamin of the spiritual world because of its ability to provide rich and soulful nutrition necessary for creativity and spiritual insight to flourish.
